"True crime" books

Does anyone know of guidance on how to class true crime books?  (I found nothing in AACR2, the RIs, or the
Subject heading manual.)  I'm picturing a sliding scale of totally factual accounts being classed with
crime in HV, and as they become more fictionalized, sliding into literature in the P's.  But how you judge
this?  I have a question about this from another librarian, and I'm not sure how to respond.

Thanks!

Dennis
